3 States Of Matter

Practice study for the Matter Test.

How is mass measured? Balance scale.
How is volume measured? Either L x W x H or Water displacement.
What are physical properties? A way to describe matter.
What are the phases of matter? Solid, Liquid, Gas, and sometimes Plasma
How do we turn a solid to a liquid Add energy.
How do we turn a liquid to a solid? Take energy away.
What is the freezing point of water? 32F or 0C.
Why can't we achieve absolute zero? Every thing is touching everything.
How do we turn a solid to a gas? We are adding energy.
What is the boiling point of water? 212 F or 100 C.
What is absolute zero? When the molecules completely stop, it is unreachable.
What is Physical change? Give an example. A change of physical properties (color, shape, size, etc.) . Example: Dipped in water, then dried, paper is still paper.
What is a Chemical change? Give an example. A change of one matter, that gives you another state of matter. Example: Pancake batter -- Pancake (Liquid to solid)
What do I know about molecules? Molecules are too small to see individually, and molecules always move.
Which would not be a CHEMICAL change? Cooking pancakes or Marker on paper? Marker on paper.
Which is not a PHYSICAL change? Vinegar and Baking soda or Ripped paper? Vinegar and Baking soda.
How would you prove something is a solution? Try to pull it apart.
Bubble bath. Salt in water. Kool Aid. What are these? Solutions.
Salad. Trail Mix. Pebbles in sand. What are these? Mixtures.
What has volume, physical properties, mass, and takes up space? Matter.
How do you check the volume of a ball? Water displacement. You need a bekar.
